Can I use different brands of ESC's in my quad?I Lost two ESC's 20A-3D Robotics due to a polarity reversal during calibration.Here near my house, Curtiba - Brazil, has a store that sells 20A ESC's…Continue

Dear Sirs,I reversed the polarity at the time of calibration of the ESC's, was very fast just touch the wire in the battery connector. Now my ESC emits no longer any sign of life :/…Continue

Dear Sirs,I'm new to UAV's.I ordered 4 - 880 Kvmotors and 4 - 20A ESC's on DIY Store for my quad.The datasheet motor recommends 40A esc but I only did this after...I have problems with the 20A…Continue

"Sometimes the caps also leak out the ends, but that can take a bit of time. Unfortunately I think most have a little linear regulator which powers the Atmel, and these won't take reverse voltage for even a fraction of a second."

"I already changed the capacitor, still does not work. Funny thing is, no smoke, everything is perfect, it was just something very quickly touched on battery connector has a small spark plug in but that's all. Does the firmware was mangled with…"

"Ok, thanks for listening ... Is there any component that I can do to try to replace save him, happened to 2 of my 4 esc's for my quad. I thought it might be the capacitor 330 / 35V, but after changing it's still dead. It was my lack of…"

"Did the capacitor let out any smoke? Is it bulging? You should be able to replace the cap if it is damaged. Jason"

"Yes, probably.  Sorry.  I think most of these don't have any reverse polarity protection."

"It would be better if I had asked this battery instead of 3S ... is the same model only changes the voltage. http://www.hobbyking.com/hobbyking/store/__8916__ZIPPY_Flightmax_2650mAh_4S1P_30C_.html"

"Ummmm I understand now, this simple calculation is very important. 4S = 14.8 v 243W / 14.8v = 16.4A I think I'll buy a 4S battery to reduce the risk of burning the ESC's but I'll do some testing temperature on wooden bench using…"

DanRZ replied to Plinio Augusto's discussion ESC'S 20A X MOTOR 880KV
"I'm not english. I'm from France, i'm learning too ... ;) With 243W and a 3S lipo, you can get the full power with 21A ( = 243W / 11.1V ). With a 2S lipo, you can get the full power with 33A ( = 243W / 7.4V ) ... You can see that on…"

"Hi DanRZ ! Sorry for my english writing errors. I'm learning. I have here at home propellers 11x45. I use them. Below the engine specifications: Model:  BC2836-9 Motor size: Ф28*36mmShaft size: Ф4.0*49mmWeight: 70g KV(rpm/v):…"

DanRZ replied to Plinio Augusto's discussion ESC'S 20A X MOTOR 880KV
"Hello, and what about props on the datasheet ? 40A surely means the motors have a certain output power, like 500W so they recommend a 40A, to exploit all the output. If you use a very large prop with high pitch, the 20A will surely have problems…"
